Review Comment:
In Flink 1.18, metricGroup was added to SourceCoordinatorContext ([PR
#21952](https://github.com/apache/flink/pull/21952/files#diff-9144631bff9092280da424a52db7a60d2e0f47e82b0c55ccbdc93ac29614d75c)
).
This change causes a serialization issue in
MixedFormatSourceEnumStateSerializer.
To resolve the problem, we mark the corresponding field as transient.
